JOHN A. HENEBERGH, OF KANSAS CITY, KANSAS.

COMBINED PORTFOLIO AND SHEET-MUSIC TURNER.

To all whom it may concern:

Be it known that I, JOHN A. HENEBERGH, a citizen of the United States,residing at Kansas City, in the county of Wyandotte and State of Kansas,have invented certain new and useful Improvements in Combined Portfoliosand Sheet-Music Turners, of which the following is a specification.

This invention relates to combined portfolios and sheet music turnersand my 0 ject is to produce a device of this character which can beutilized for the convenient reception and storage of sheet music andwhen open placed upon the rack of a piano to hold and turn the music tobe rendered.

A further object is to produce a device of the character outlined whichoperates efiiciently and reliably and which is of ornamental and compactconstruction.

WVith these general objects in view theinvent-ion consists in certainnovel and peculiar features of construction and organization ashereinafter described and claimed; and in order that it may be fullyunderstood reference is to be had to the accompanying drawings, inwhich- Figure 1, is a view of the combined portfolio and sheet musicturner in opened position and arranged for turning a sheet or sheets ofmusic. Fig. 2, is an enlarged view of a portion of the lower end of thesame. Fig. 3, is a vertical section on the line III'III of Fig. 2. Fig.4, is a vertical section on the line IVIV of Fig. 2. Fig. 5, is asection on the line VV of Fig. 1, with the sheet music in operativeposition.

In the said drawings where like reference characters indicatecorresponding parts in all the figures, 1 indicates a portfolio equippedwith loop handles 2 for convenience of carriage and susceptible ofclosing like a book along its vertical center.

Secured to the inner side of one member of the cover at one side of thebend or hinge portion thereof is a metal plate 3 bent outward slightlyat its lower end to form a keeper 4 for engagement with a bar 5 pivotedto a screw 6, secured to the other member of the cover, a clamping nut 7engaging the screw to secure the bar 5 against accidental pivotalmovement. When the book is opened, the bar 5 is swung upon pivot 6,until it bridges the hinge portion of the portfolio and is engaged withthe keeper 4 so that the latter shall prevent the bar from opening andthus cooperate with the same in Specification of Letters Patent.

holding the portfolio open, the position which it must occupy whenholding sheet music in operative position upon a piano rack or othermusic rack or support.

8 1s a bar parallel with the cover members and secured to the centralportion of the hinge portion of the portfolio and provided near the endsof the latter with upwardly pro ecting arms 9 forming journals andsupports for a screw rod 10 engaged at its threaded end by a nut 11.

One or more sheet carrying frames are each constructed as follows :-l2is a tube fitting telescopically on a rod 13. To prevent accidentalslippage the rod is provided with a leather washer or friction disk 14,engaging the interior of the tube. At the lower end of the tube andupper end of the rod are hinge flanges 15 pivotally engaging pivot rod10, and projecting outward from the flanged ends of said tube and rodare parallel arms 16, the upper arm having a rod 17 and the lower arm atube 18 fitting telescopically together, it being noted by reference toFigs. 1 and 3, that the flanges 15 of one sheet-carrying frame fitagainst the inner sides of the corresponding parts of the other sheetcarrying frame. The lower arms 16 of said frames are provided withupwardly opening clips 19, and the upper arms are provided with pivotedclamps 20, of U-shape as shown, it being noted by reference, to Fig. 2that the clip 19 of the rearmost sheetcarrying frame is at the outerside of the latter and that the clamp 20 of said frame is pivoted to theunderside and its free or clamping end overlaps its upper side. Thereverse is true of the other sheet-carrying frame, that is the clip 19is at the underside of the same when occupying the position shown inFig. 2, and the clamp 20 ispivoted to the upper side and its free end isarranged at the opposite side. To hold said frames in the position shownin Figs. 1 and 2, a bracket 21 is secured to the right hand member ofthe cover and carries a horizontal bolt 22 engaged by a nut 23. Pivotedon the bolt at the right hand side of the upwardly projecting arm of thebracket is a dog 24 having a depressible handle 25, a spring 26 mountedon the bolt and secured at its opposite ends to the standard and saidhandle tending to move the dog in the direction indicated by the arrow,Fig. 4, the dog below its pivot having an extension 27 to bear againstthe foot of thebracket to limit the movement imparted to the dog by saidspring. Projecting laterally from saic dog is a pin 28 in advance of asimilar dog 29 having a handle 29, pivoted on the bolt at the oppositeside of the standard, the catch end of the dog projecting to a higherplane than the corresponding end of the first-named dog for engagementwith the upper sheetcarrying frame, whereas the first-named dog isadapted for engagement with the lower sheet-carrying frame as shownclearly in Fig. 4, and to hold the dog 29 in operative position, thatis, pressed in the direction indicated by the arrow, a spring 30 issecured on the bolt and at one end engages said dog and at the other thestandard 21, the spring holding the second dog pressed upwardly againstpin 28, as shown clearly in the last-named figure. By this arrangementit will be seen that when the frames are successively swung to theposition shown in Fig. 2, the undermost frame engages dog 29 andrepresses the same and the other dog and as it clears the latter the twodogs spring forward to permit dog 24 to engage and hold the frame in theposition described. The other frame is then swung to the position shownin Fig. 2, and engages and represses dog 29, said dog snapping back oversaid frame and holding it in the position shown in Fig. 2.

31 is a coiled spring mounted on hinge rod 10 between the lower arm. ofbar 8 and the washer 32 fitting on said red, one end of the spring beingsecured to the uppermost or foremost frame and the other end to the arm9. A. similar spring 33 is mounted on the hinge rod between washer 32and a second washer 34; and the ends of said spring are secured to theundermost frame and the adjacent arm 9. The arrangement is such that theoperation of dog 29 withdraws the same from the path of movement of theforemost or uppermost frame to permit the spring 31 to swing said framefrom the position shown in l ig. 1, full lines, to the position shown insaid figure in dotted lines without affecting the companion orunderlying frame. On operating the other dog the rearmost frame iscaused by its spring 33 to perform a similar movement.

The preferred way of arranging the music, assuming that it consists oftwo double sheets, is to place the cover sheet 35 upon the members ofthe portfolio as shown in Fig. 5, the inner sheet 36 is then fitted onthe hinge red as shown in the same figure so that one leaf shallunderlie the foremost or topmost frame and the other sheet shall overliethe undermost or rearmost frame, the said inner sheet being arrangedwith the lower edges of its leaves fitting in hooks 19, and the upperedges of its leaves clamped against their respective frames by theclamps 20. By this arrangement it will be seen that the operation of theframes as described will effect tne automatic turning of the leaves. Thehinge frames are telescopic as described to adapt them for use withsheets of different sizes.

If it is desired to hold a single sheet spread open upon the cover, itcan be ar ranged thereon as indicated at 35, Fig. 5, and rest at itslower edges in hooks 37 secured to the cover members and be overlappedat its upper end by the pivoted clamps 38 pivoted to said cover-members,and for conveniently carrying a number of sheets without danger of loss,the same may be secured in the portfolio in the manner last described,that is by means of the hooks 37 and clamps 38.

From the above description it will be ap parent that I have produced acombined portfolio and music sheet turner possessing the features ofadvantage enumerated as desirable and I wish it to be understood that Ireserve the right to make all changes properly falling within the spiritand scope of the appended claim.

I claim:

In a leaf-turning device, a supporting frame, spring-actuatedleaf-turners mounted thereon, a pivot bolt carried by said frame,springactuated dogs of varying lengths mounted on said bolt, theshortest of said dogs being provided with step meanscontacting with theframe for limiting its pivotal movement under the action of its springand also with stop means for lim-- iting the pivotal movement of thenext longer, dog of the series under the action of its spring, said dogsbeing adapted to retain and successively release said leaf-turners fromtheir initial position.

In testimony whereof I atlix my signature, in the presence of twowitnesses.
